Dragon Shouts

A major part of the combat system in Skyrim are the Dragon Shouts. These are powers passed down by the dragons, usable only by a select few including the Dragonborn. Any character can use them and they have devastating effects in battle. Some are utility spells that can be used while traversing the world of Skyrim.

Dovahkiin using the FusRoDah (Unrelenting Force) dragon shout

In Dragon language, Dragon Shouts are called Dovahzaan in the same way that Dragonborn is called Dovahkiin. This is a complete list of all the Dragon Shout locations in Skyrim.

There are 20 dragon shouts in TESV: Skyrim and each shout has 3 words of power. To use a dragon shout, the character must find at least one word of power and absorb a Dragon Soul(per word of power). Each word of power in a shout improves its effects. Many of these words are learned from Word Walls located in different parts of Skyrim. You will find the Word Wall locations by traveling the word of Skyrim. Some are taught by the Greybeards in High Hrothgar and some are gained by doing the Main Quests.
